Abstract

Magnesium intercalated vanadium oxide xerogels, Mg_0.1 V₂ O ₅•2.35H₂ O and Mg_0.2 V₂ O ₅•2.46H₂ O were synthesized using an ion removal sol gel strategy. X-ray diffraction indicated lamellar ordering with turbostratic character. X-ray absorption spectroscopy indicated greater distortion of the vanadium-oxygen coordination environment in Mg_0.2 V₂ O ₅•2.46H₂ O. Elemental analysis after cycling in Li⁺ or Mg²⁺ based electrolytes revealed the magnesium content was unchanged, indicating structural Mg2+ are retained. The Mg_0.1 V₂ O ₅•2.35H₂ O material displayed high voltage, energy density, and discharge/charge efficiency, indicating promise as a cathode material for future magnesium based batteries.
